Hi Charles,

gen-snmp-subdriver.sh simply hasn't done its job, for some reasons.
well, 1 clear is that's it not a completed effort... at all
but, still IIRC, it should have produced at least a bit more

@Jason: how have you called the script?
could you please also send an archive including:
- the results of the adapted commands on #L73, #L74
https://github.com/networkupstools/nut/blob/master/scripts/subdriver/gen-snmp-subdriver.sh
- your mib file

cheers,
Arno
